CLASSA

Compañía de Líneas Aéreas Subvencionadas, meaning 'Subsidized Airlines Company', mostly known as CLASSA, was a Spanish airline based in Madrid, Spain.

The airline was established as part of the Miguel Primo de Rivera government's efforts to establish state-controlled monopolies controlling essential services. As had been done with CAMPSA and with CTNE, a monopoly was created by merging existing Spanish air transport companies. CLASSA's inaugural flight took place on 27 May 1929 between Getafe (Madrid) and Sevilla although regular operations wouldn't officially start until November.

CLASSA ceased operations in 1933, the second year of the Spanish Republic, and in those years did not have any air accidents.
